SULKY-PLOW.

Application filed November 28, 1919.

T 0 all w/ zom it may concern.

Be it known that I, SHELDON S. SPIRE, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Sulky-Plow, of which the following is a specification.

This invention relates to sulky plows and has for its object a particularly simple and etficient means for controlling the castering of the caster or furrow wheel including ahandle which does not change its position relatively to the operator during castering of the wheel.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In the drawings Figure 1 is a plan view of a sulky plow embodying my invention, parts being omitted.

Fig. 2 is thereof.

Fig. 3 is a detail plan view of the caster wheel, the same being shown as castering in one direction.

ig. 4 is an enlarged sectional view on line 4-4, Fig. 2.

Fig. 5 is an enlarged sectional view on line 55, Fig. 3.

This sulky plow may be of any suitable form, size and construction and as here shown comprises a frame 1 having suitable bearings for crank axles 2, 3, there being two axles 3 one directly above and in parallelism with the other.

4 is a ground wheel mounted on the spindle 5 at the outer end of the axle 2.

6 is the caster or furrow wheel. 7 is the rear wheel.

The caster wheel 6 is mounted upon a suitable axle having a spindle portion 8 on which the caster wheel rotates and an u wardly extending portion 9 journaled or swiveled in an upright bearing 10. This bearing 10 also has transversely extending horizontal bearings 11 for the spindles 12 at the outer ends of the axles 3.

he means for controlling the castering of the wheel 6 as here shown comprises a member or sector 13 mounted on the upper end of the portion 9 of the caster wheel axle, and means coacting with the sector 13 to normally hold the caster wheel in a predetermined position usually in a straight poa fragmentary side elevation Specification of Letters Patent.

sition or parallel with the line of draft, said means being normally fixed from lateral swinging movement as the caster wheel swivels. As here shown, the sector 13 is formed with a single notch 14 and with plane faces 15 on opposite sides of the notch, said faces being here shown as concentric the upright portion 9 of the caster wheel axle. The means for coacting with this sector comprises a spring pressed pawl 16 fixed from turning moveof the plane faces 15 after it has been withdrawn from the notch and the caster wheel is swiveling in one direction or the other.

As here shown, the spring pressed pawl 16 is movable in a suitable guide or barrel 7 mounted upon a support or bracket 18, the spring 19 being located in the barrel 17 and encircling the stem of the pawl and pressing in one direction on a collar 20 on the pawl and at its other end against the rear end of the barrel. The pawl is moved comprlses a bracket mounted on the upper end of the bearing 10, it being here shown as having a split bearing 23 which is clamped onto the bearing 10 by means of a bolt and nut 24, 25. The bracket can therefore be adjusted i as will be understood by those skilled in the art. For instance hillside plowing requires difl'erent normal position of the caster wheel from level ground plowing. The adjustment of the support is extending into wheel casters slightly the pawl rides on one ing and having clamping means by which or the other of the surfaces-l5. it is securedto thebear-ing,the-support Then the plow has been turned to the being adjustable to-different radial posidesired position and is proceeding in a tions about the bearing, a sector mounted 5 straight line the caster wheel turns back to "upon the upper end of said portion of the its normal position and the spring pressed axle and overlying the said support, the secpawl automatically latches in the notchand tor having a notch and plane faces on oppoholds the caster wheel from further castersite sides of the notch, a spring pressed pawl ing. The handle controlling the castering is mounted on the support and coacting with 10 always within the same distance from the the sector and movable into the notch thereseat, as it does not swing as the caster wheel of, and a handle mounted on said support swivels. and connected to the pawl to withdraw the What I claim is: same against the action of its spring, sub- In a sulky plow, the combination of a stantially as and for the purpose described.
